Abstract: An aircraft electromechanical actuator control system for an aircraft having a direct current (DC) voltage bus includes an actuator controller that is coupled to receive a first DC voltage from the aircraft DC voltage bus, where the first DC voltage has a first voltage magnitude. The actuator controller selectively supplies AC voltage to an electromechanical actuator and includes a bidirectional DC/DC converter, an inverter, and actuator control logic. The bidirectional DC/DC converter receives the first DC voltage and supplies a second DC voltage having a second voltage magnitude that is less than the first voltage magnitude. The inverter receives the second DC voltage converts it to the AC voltage. The actuator control logic receives actuator commands and supplies inverter control signals to the inverter.

Abstract: A system configuration significantly reduces the number of interconnections needed between an electromechanical actuator (EMA) and an EMA controller (EMAC) while maintaining redundancy and other safety aspects needed by the target application. This allows simplification of communication interfaces between multiple sensors in the EMA and EMAC and unification of the interface to multiple sensors inside the EMAC, leading to cost and weight reduction that can be significant for many aerospace products and applications, including unmanned vehicle (e.g., UAM/UAV) applications.
